What do I buy?

I always believe in Pre-Mix, believe I've said that before....but... I did see a big Suzuki Super Six seize up when the oil gelled in the oil injection lines. If you're pre-mixing, it probably isn't that important that you use the manufacturers oil. Some folks on this site believe in the Suzuki oil, maybe I do too in a Suzuki from what I've seen. My humble opinion is that if you pre-mix, an oil rated at TCW3 is probably OK. If you're going to use the injection system, go with the manufacturers recommended oil.

The shame about the big Suzuki was that it had ran flawlessly for 3 years on Suzuki oil. After a several month rest over the winter it failed on the first trip. The major brand oil had turned to a blue gel in the injection tubings blocking flow. I was there, and I pulled the powerhead down....it ruined the whole powerhead including the crank. $3 grand later everything was OK.
